According to the formats description in videodev2.h Y210, Y212 and Y216 are YCbCr packed formats. For each Y2xx format, xx bits of valid data occupy the MSBs of the 16 bit components, and 16-xx bits of zero padding occupy the LSBs. The Y210 and Y216 formats are missing an entry in the v4l2_format_info[] table. Add it.
